Profile Information

In der Lehre betreut das Institut Studierende des Maschinenbaus und des Bauingenieurwesens, sowohl im Grundlagenfach "Festigkeitslehre" als auch in den Vertiefungsfaechern "Finite Elemente", "2d-Bauteile (Scheiben, Platten, Schalen)", "Plastizitaetstheorie", "Elastizitaetstheorie i und ii", "Operatorkalkuel fuer Ingenieure", "Wavelets", und "symbolische Berechnungen". In der Forschung beschäftigt sich das Institut mit der Weiterentwicklung der numerischen Methoden (Finite Elemente auf Polynom- und/oder Waveletansaetzen) der Festkörpermechanik sowie mit Materialtheorie (einschließlich Thermodynamik) auf Mikro-, Meso- und Makroebene. Dabei wird das anisotrope und das zeitabhaengige (viskose) Verhalten untersucht, sowohl im elastischen als auch im anelastischen Bereich. Damit können technologische Umformprozesse (Walzen, Schmieden, Ziehen, Extrudieren, ...) wirklichkeitsnah numerisch simuliert werden. Die Erstellung der Rechnerprogramme erfolgt innerhalb der "Materialtheorie" durch den Rechner selbst, mittels "symbolischer Berechnung". Die Arbeitsschwerpunkte sind: Materialtheorien (einschließlich Thermodynamik) auf Mikro-, Meso- und Makroebene, numerische Verfahren (Finite Elemente, Wavelets), symbolische Berechnungen, Anwendung auf thermodynamische Festkörperprobleme (technologische Umformprozesse). Short Description: With regard to education the institute instructs students of mechanical engineering and civil engineering, respectively, in the basic subjects 'mechanics of materials` as well as in the continuing subjects 'finite elements`, '2-dimensional structural members (plates and shells)`, 'theory of plasticity`, 'theory of elasticity 1 & 2`, 'operator calculus for engineers`, 'wavelets`, and 'symbolic computations`. With regard to research the institute occupies itself with the continuing development of numerical methods (finite elements on polynomial and/or wavelet ansatzfunctions) in solid mechanics and with matherials` theory (thermodynamics included) on a micro-, meso- and macro-level, respectively. Here, the anisotropic and the rate-development (viscous) behaviour is investigated, in the elastic region as well as in the inelastic one. Thus technological forming processes (like rolling, forging, drawing, extruding, ...) can be simulated realistically.
